To allwhom it may concern:

Be it known thatl, DONALD M. Gites, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and use ful Snubbing Device for Dye Sticks, of which the following is a specification.

My invention has reference to skein dyeing machines for yarns or like spinnable material, of the Ferris-wheel type, as disclosed in Patent Number 1,146,324: dated July 13, 1915, and is directed more particularly to novel mechanism, hereinafter referred to as a snubbing device, for permitting turning of the outer dyesticks in one direction and preventing retrograde rotation thereof.

The typeoi machine referred to includes any machine for chemically treating spinnable material, such as a skein dyeing machine consisting of a dye vat usually semicylindrical in shape, a reel revolving in the vat, means for supporting the skeins of yarn on the reel, consisting of two concentric circular series of yarns supporting or dye sticks (on each end of the reel) between which the skeins of yarn are stretched, means for turning the outer sticks, and means for preventing retrograde rotation of the dye sticks. The reel revolves in the dye vat and as each outer stick passes a certain point, it is tripped or given a quarter turn so that the position of the yarn on the sticks is constantly changed during the dyeing operation to insure thorough and uniform action thereon by the dyestufi or liquor.

The present invention is directed more particularly to a snubbing device normally to prevent retrograde or reverse rotation of the dyesticks after tripping so as to progressively subject all parts of the yarn to the dye liquor while also being adapted to pen mit rotation of the dyesticks in the 'opposi to direction, or in either direction.

For the purpose of illustrating my invention, I have shown in the accompanying drawings forms thereof which are at present preferred by me, since they will give in practice satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can he variously arranged and organized and that my invention is not limited to the precise arrangement and organization or these instrrnnentalities as herein shown and described.

corresponding parts in the figures.

Referring to the drawings l designates a portion oi reel adapted to be arranged in asuitable dye tub or vat, not shown, and designates a well known tripping device employed.

3 designates a hub which is attached to the collar l, the former being mounted on the driving shaft 6 and the latter beingseured as at 5 to one 01" the spiders or spokes oi the reel, which latter supports inner and outer bearing rings 8 and 9. The reel is adapted to be suitably driven or rotated on the shaft 6 and as shown, the outer ring 9 is in the form of a gear having teeth 10 adapted to mesh with a suitable pinion, by

which it may be revolved. The resilient tripping device 2 provided is suitably supported in the vat.

The bearing rings 8 and 9 are oppositely arranged and provided on each end of the reel with bearings for two parallel inner and outer concentric circular series of dyesticks 1i and 12. The inner sticks are preferably round in cross section while the outer sticks are preferably angular or square in cross section, and the skeins of yarn to be dyed are suspended and stretched between the sticks or members of the outer and inner series double reels, as indicated in dotted lines in Figure l oi the drawings.

Each outer or angular stick is rotatably mounted at one end, as shown and described in the patent above mentioned, being preferably provided on one end with a round ferrule not shown and on the other with a 'in a journal so constructed that the stick may be readily put in place or removed, while at the other or square end provided with ferrule 13 a socket hearing or ratchet cup 16 is provided journaled in ring 9 and I having a square socket 17 receiving and supporting the squared end in iixed relation thereto. The cup 16 is of circular cross section mounted in apertures 14, provided at one end with a ratchet or star wheel 18, at the inner end of socket 17 with an internal annular stop shoulder or flange 19 and at the other end with an external circumscribing rib 2O.

Bosses 15 form spacers between the star wheels 18 and gear ring 9. A retainer 21 is seated on the barrel of cup 16 against ring 9 to retain the cup in position, and a helical spring 22- preferably of wire or square cross section iswrapped or snugly mounted around the barrel of the cup, which is turnedto a smooth cylinder, one end of the spring being made fast to the ratchet cup supporting members or ring 9 and the other end abutting shoulder 20. As illustrated, the spring ratchet forming a part of the snubbing device or gripper, is composed of sev'eral'coils and has its terminals provided with eyes 23 and 24, the former of which is anchored to the ring 9 as indicated at 25 and the latter of which is free, but preferably bent slightly inwardly with the last or adjacent coil, as indicated at 26.

In theoperation of the machine, the reel is driven as described, or in any other customary way, and as the star wheels pass the tripper T, each star wheel and its outer stick is tripped or given a quarter turn to move the yarn a corresponding distance so that all parts of the skein will have equal exposure to the dye liquor aspreviously stated.

The tripper will operate in the usual way,

the spring of the trip device taking up jar or shock. As the star or ratchet wheels 18 are tripped, and the sleeves or cups 16 turned,

the outer dyesticks 12 will be correspondingly turned to impartthe necessary movement to the yarn, this being facilitated by the square cross-section of the sticks and the conformation and fitting grip of the yarn thereto. In all prior machines, retrograde r0ta tion of the journaled socket bearings or cups was prevented by spring or gravity-actuated pawls, which are not only readily worn and soon become inoperative for the purpose intended, but do not permit turning of the cup or hearing socket in a backward direction when desired. By the present device r0- tation of the cup and stick in a forward direction is permitted, butwhen tension of the yarn acts to cause backward motion, the coils of the spring, due to the friction between the spring and barrel wraps tightly on the barrel of the cup and grips or seizes it so tightly as to prevent any backward motion. The principle of action is the same as snubbing a rope around a post, in which a flexible member surrounds a cylindrical form to prevent rotation of the cylinder in one direction and permit rotation in the opposite direction. Several coils of wire are necessary to produce the desired effect, but it is found in practice that by bending the last coil, which has the free eye'25, slightly toward the center of the coil and stepping or canting the coils, a fewernumber of coils is required. Attimes,"itis desirable to turn the cup in a backward direc tion, and'for this purpose, eye 24 is provide ed on the end of the free or last coil of the spring, so that'the end of the spring may, when desired, be manually lifted'away from the ratchet cup barrel, when the bearing socket or cup and stick, as well as the yarn, may be readily moved in a backward direction. While the snubbing device is shown applied to a dyeing machine, it "may be applied, and the scope of the invention includes its application, to any like device, but more especially to machinesyfor chemi cally treating spinnable material,- chemicaltreatment including any treatment by which the condition of the material is changed in nature or appearance, weight or degree of moisture, such as dyeing, bleaching, scouring, rinsin drying, mercerizing, weighing etc., and spinnable material is understood to be any material which may be spun into a yarn or made into a filament.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a machine for chemically treating spinnable material, a stick adapted to support a skein, a stick rotating member, and a snubbing member arranged to preventrotation in one direction and to permit rotation in the opposite direction.

2. In a machine for chemically treating spinnable material, a stick, a stick rotating member, a snubbing member arranged to normally prevent rotation of said stick in one direction and to permit its rotation in the opposite direction, and means for enabling said stick to be rotated in either direction when desired.

The combination of stick, a stick turning mechanism for dyeing, bleaching and scouring machinery, means surrounding the stick turning means'and frictionally gripping'thesame in one direction to prevent retrograde motionthereof and adapted" to permit motion thereof in the opposite direction, and means for enabling said stick to be rotated in either direction.
